    Abstract: A technology that can adaptively control an access mode according to a shared band or an unlicensed band used by an adjacent communication system. An access mode controlling apparatus includes a band recognition unit to recognize a usage rate of an unlicensed band or a shared band that is used by an adjacent communication system of a target communication system; a mode determination unit to determine, as an access mode, any one of a contention access mode and a contention-free access mode, based on the usage rate of the unlicensed band or the shared band; and an information transmitter to transmit mode information associated with the determined access mode to member nodes or a base station of the target communication system.

    Abstract: The present application discloses a system and a method for tag estimation and anti-collision in an RFID system, which can estimate an exact number of tags within an RF area and can rapidly identify tags by using the estimated number of tags in an RFID system. The system includes an RFID reader and RFID tags. The RFID reader includes an identification means, a collision management means, a tag number estimation means, and a reader control means. The RFID tag includes a tag communication means, a message reading means, a counter management means, an information storage means, and a tag control means. The disclosed system and method can prevent occurrence of too many idle times slots in the DFSA and too many initial collisions in the binary tree scheme, and thus can identify a large number of tags at a high speed with a small number of time slots.

    Abstract translation: 本申请公开了一种RFID系统中的标签估计和防碰撞的系统和方法，其可以估计RF区域内的标签的确切数量，并且可以通过使用估计的RFID系统中的标签数量来快速识别标签。 该系统包括RFID阅读器和RFID标签。 RFID读取器包括识别装置，碰撞管理装置，标签号估计装置和读取器控制装置。 RFID标签包括标签通信装置，消息读取装置，计数器管理装置，信息存储装置和标签控制装置。 所公开的系统和方法可以防止DFSA中发生太多空闲时隙，并且在二叉树方案中发生太多的初始冲突，因此可以用少量时隙高速识别大量的标签。
